Brothers Mark Pearcy and Jeffrey Kurt Pearcy, who were arrested May 29, have been charged with tampering with evidence and accessory after the fact, said bureau spokesman Josh DeVine.

DeVine wouldn't comment further on the evidence or circumstances around the charges.

"Out of respect for the judicial process, we cannot speak to the particular possible pieces of evidence in this case," he said in an e-mail to The Jackson (Tenn.) Sun. "We continue our work to follow the leads wherever they might lead. We won't stop until we find a sense of justice and closure for the family and friends of Holly Bobo."

According to Jeffrey Pearcy's attorney, Olin Baker, the charges and claims against Jeffrey Pearcy are untrue.

According to the affidavit for Jeffrey Pearcy, investigators believe he has "shown a visual recording on an electronic device to an individual. According to the witness, this visual recording shows information that will prove to be beneficial in the prosecution of a current on-going investigation being conducted by the Tennessee Bureau of Investigation."

The affidavit doesn't mention whether the charges are in relation to the Bobo case.

Investigators believe that Jeffrey Pearcy has possession or has knowledge of where the video is, according to the affidavit.

The affidavit states that Jeffrey Pearcy is an "accessory after the fact due to his conduct concerning the concealment of evidence into the investigation."

Tampering with evidence is a class C felony and accessory after the fact is a class E felony.

Jeffrey Pearcy, 42, is currently being held in Henderson County without bond.

Mark Pearcy was transferred from Decatur County to Carroll County last week and also is being held without bond.

According to online records, Mark Pearcy, who is not represented by Baker, registered as a sex offender in 2000 for statutory rape.

Bobo was abducted the morning of April 13, 2011, from outside her home in Darden, Tenn. Her brother told investigators he saw a man wearing camouflage walking her into the woods.

Zachary Adams was indicted in March on charges of especially aggravated kidnapping and first-degree murder.
